Covering the whole development process for the global biotechnology industry

Bioprocessing begins upstream, most often with culturing of animal or microbial cells in a range of vessel types (such as bags or stirred tanks) using different controlled feeding, aerating, and process strategies.

Beginning with harvest of material from a bioreactor, downstream processing removes or reduces contaminants to acceptable levels through several steps that typically include centrifugation, filtration, and/or chromatographic technologies.

Drug products combine active pharmaceutical ingredients with excipients in a final formulation for delivery to patients in liquid or lyophilized (freeze-dried) packaged forms — with the latter requiring reconstitution in the clinical setting.

Many technologies are used to characterize biological products, manufacturing processes, and raw materials. The number of options and applications is growing every day — with quality by design (QbD) giving impetus to this expansion.

Even as it matures, the biopharmaceutical industry is still a highly entrepreneurial one. Partnerships of many kinds — from outsourcing to licensing agreements to consultancies — help companies navigate this increasingly global business environment.

January-February 2019

Greetings from the BPI editorial staff — we wish you a healthy and prosperous 2019! Beginning with a combined January–February issue somehow makes the year seem to be speeding by right from the start. We are immersed now in the first radical redesign of our magazine since the publication’s founding in 2003. Some aspects proceed smoothly; others, not so much. You see with this issue a new cover design that ties us in with our KNect365 event brands. You’ll see…

The biopharmaceutical industry has seen strong growth over the past 15 years, with a compounded annual growth rate (CAGR) of 6.7%. However, if you look at that growth in five-year intervals, it becomes apparent that the rates have begun to decline in many countries. Companies have withdrawn somewhat and put initiatives into place to curb further increases in the cost of drugs. The CAGR fell from 8.7% for the period of 2002–2006 to only 3.1% for 2012–2016. In our yearly…

Immunotherapy seeks to harness the power of our human immune system to fight disease. In this rapidly evolving field, collaboration among different stakeholders is essential to bringing new treatments to market. Patient advocacy groups, researchers, hospitals, manufacturers, and government entities all are working together to translate promising new research into life-saving products. Types of immunotherapy include monoclonal antibodies (MAbs) and antibody derivatives, checkpoint inhibitors (immune-modulating proteins), cancer vaccines, T-cell therapies, and cytokines — so the approach involves a range of…

The biopharmaceutical industry is under pressure to generate value for shareholders and find innovative therapies while driving down development and manufacturing costs. As the industry considers more flexible and scalable production solutions for patients, new therapies will continue to be developed faster than ever before. These products will need to rely on robust and reliable manufacturing solutions. To deliver on that challenge, streamlining manufacturing processes will be necessary so that many lots of drug substances can be manufactured, stored, and/or…

Human plasma is a complex mixture of biomolecules such as serum albumin, immunoglobulins, coagulation factors, and others (1). These important protein biomolecules often are present at low levels or lacking in affected patients with certain life-threatening conditions. To extract those valuable proteins, a number of purification methods have been developed over time. Plasma fractionation can be traced back to the middle of the 20th century, when Edwin Cohn of Harvard University developed the first industrial process to purify proteins from…

In the past 20 years, novel therapeutics have become a major segment of biopharmaceutical research and development, particularly for immune disorders and cancer. Progress in gene therapies could bring cures for once deadly and debilitating genetic disorders such as hemophilia or muscular dystrophy. Biologic drug products offer potential treatments that have not been possible with traditional (chemistry-based) approaches. But such products also are more difficult to produce cost effectively at an industrial scale because of the intricacies associated with biological…

Host cell proteins (HCPs) originate from host organisms that are used to produce biopharmaceutical products. They are in-process contaminants that must be minimized during downstream process operations. According to regulatory agencies, the maximum permitted level of total HCP in a biopharmaceutical product is 100 ng per mg (100 ppm) (1). HCPs can decrease drug efficacy and pose a risk to patient safety because they can bring on undesirable immune responses. Thus, HCPs are a critical quality attribute that should be…

The biopharmaceutical industry’s need for rapid, accurate concentration measurements of protein-containing products is critical. The protein-concentration assay measures ultraviolet absorption at 280 nm (A280) and usually is performed both as an in-process test and for product-release testing. The SoloVPE system can analyze samples across a wide range of target concentrations without the need for labor-intensive and error-prone dilutions. Slope Spectroscopy methods provide companies with a universal platform for determining protein concentration for all in-process, clinical, and commercial methods. During in-process UV…
